I can’t quite imagine right now what that’s supposed to look like.
150sqm with 4 bedrooms, guest / office, guest WC with shower and large utility room, 2 home office spaces – honestly, I’m surprised you don’t also have a pantry and sauna on your wish list. That 8sqm kitchen – will that be enough for you in the long run? The bedroom closet – can you even stand in front of it and open it?
So I took the basic idea and sorted it a bit. Even though I went with 8.70m depth, only a 50cm wardrobe fits. Utility room 7.7sqm will probably be too small for you, but I find the 3m kitchen even worse. I really ask myself: Is this still sensible or should one rather leave it?
